Automatic Door Bottom #367 Data Sheet

| More

 

Our automatic door bottoms utilize a flat spring mechanism, which activates when the door is closed, lowering a neoprene seal insert against the floor or saddle. A protruding, hinge-side "plunger" is compressed by the frame as the door closes to activate the spring. The seal then drops in a scissors like motion from the hinge side, adjusting to the floor from a pivoting point. This motion ensures a smooth drop without drag for a tight seal, even on an uneven floor. As the neoprene seal compresses, it forms a tight, secure seal against the saddle or floor. The seal reacts automatically as the door is opened.
